Biology Question on Photosynthesis in higher plants
How many ATP and NADPH2 are required for the synthesis of one molecule of Glucose during Calvin cycle?
A
18 ATP and 12 NADPH2
B
12 ATP and 16 NADPH2
C
18 ATP and 16 NADPH2
D
12 ATP and 12 NADPH2
Answer
18 ATP and 12 NADPH2
Explanation
Solution
The Calvin cycle, which is part of the light-independent reactions of photosynthesis, uses ATP and NADPH2 (reduced form of NADP+) generated during the light-dependent reactions to fix carbon dioxide and produce glucose. Specifically, it takes 18 molecules of ATP and 12 molecules of NADPH2 to synthesize one molecule of glucose.
Therefore, The correct option is (A): 18 ATP and 12 NADPH2
